If you create a line feature class in a geodatabase, an additional field is added to the feature class automatically to record the length of the line. If you create a polygon feature class, two additional fields are added automatically to record the length (perimeter) and area of each poly...
Create a set of feature subclasses in a single feature class. Subtypes are often used to manage different behaviors on subsets of the same feature type. Domains Specify a list or range of valid values for feature class attributes. Domains help ensure the integrity of your data and are often ...

A feature class that defines the location (e.g. outline or bounding box) of each feature. There are two major steps in feature classification. We first export training samples based on the geographical extent of each feature. Once the training samples are exported, it can be used as the tr...
The CIM_SoftwareFeature class represents a particular function or capability of a product or application system. This class reflects a level of granularity that is meaningful to a user of a product rather than the units that reflect how the product is built or packaged (captured using a CIM_...
